Castor

Headquartered in Amsterdam, Castor is a cloud-based e-clinical data platform that can be used for a range of tasks and processes during a clinical trial. It offers four solutions: 1) electronic data capture (EDC) to capture and process data from multiple sources including researchers, 2) electronic patient-reported outcomes (ePRO) to collect and manage patient-reported data on a centralized platform, 3) e-consent - to enable patients to be recruited, screened, and enrolled remotely, and 4) a decentralized clinical trials (DCT) platform to assist operators with managing DCT technologies and devices through a central platform. The company’s solutions are targeted at industries like biotech and pharma, diagnostics, and clinical research organizations. Its solutions are built in line with industry-standard compliance and data protection standards including HIPAA, GDPR, and ISO 27001.

Castor aimed to collect enough clinical trial research data to enable the reuse of data for AI-driven clinical trials, which would lower the costs of operating clinical trials and reduce the time taken to bring new drugs to market.

In February 2024, the company partnered with Microsoft to use Microsoft Azure to bring modern AI to clinical trials. The feature was released to help Castor users develop their studies faster by simplifying complex tasks in the study build process. The company additionally noted that it was planning to release its first in a line of Practical AI features to all its users in public Beta.
